SN74HC21DRE4 Overview

Shipped in 14-SOIC (0.154, 3.90mm Width), the part is easy to ship overseas. High reliability is ensured by the advanced packaging method Tape & Reel (TR). Using AND Gate logic, it functions. In order for the part to function correctly, a voltage of 2V~6V is required. Temperatures around -40°C~85°C are extended for operation. Surface Mount is the location of the part. 5.2mA 5.2mA output current is 5.2mA 5.2mA in the high or low state. There are several in the 74HC series. Totally, there are 14 terminations. In addition to 2 functions that significantly boost the user experience, the part includes 2 other features. I would like to point out that this chip is part of HC/UH. 74HC21 can be used to search for device variants. A total of 14 pins are injected into the part body. Many applications include this logic device with a Surface Mount mounting. For details about the functions of 14 pins, please refer to the datasheets. A 4 input is supported by the part. The current flowing through quiet parts is 2μA. A load capacitance of 50pF is provided by the part. This device requires a minimum voltage of 2V. As soon as Vsup reaches 6V, the maximal supply voltage is achieved. It includes the industry TR method. Device output current is 5.2mA. In this device, there are 1 outputs. Operation is based on 2 elements in total. Typical operating voltages for the chip are specified as being z volts when it is first manufactured.
